Archivi digitali integrati per la conoscenza condivisa e la documentazione del patrimonio architettonico delle aree interne: il caso degli opifici idraulici della valle dell’Aterno

The built heritage that characterizes many of Italy’s inner areas consists of fragile and often overlooked structures, frequently excluded from systematic documentation processes, that need to be safeguarded and enhanced. This research addresses that context by proposing an interdisciplinary methodological approach aimed at creating an integrated digital archive to document the built heritage of the central Apennines, with a particular focus on the mills of the Aterno Valley (Abruzzo). The goal is to guide processes of material conservation and ensure the transmission of historical memory to future generations. Innovative digital tools have been tested to facilitate knowledge sharing through democratic participation, data representation, and archiving, with the aim of building an information system capable of aggregating and correlating heterogeneous data. The adopted approach combines GIS technologies, HBIM modelling, and web-based platforms, following principles of semantic interoperability and long-term updatability. This has led to the definition of a digital archive oriented toward the stratified representation of information, the relationships between structures and the surrounding landscape, and potential connections with local communities. The results highlight how heritage digitization and the proposed methodology can lead to the development of participatory tools that support knowledge sharing and the construction of a narrative respectful of shared memory, which can assist not only in the preservation of cultural assets but also in the cultural regeneration of inner areas.
